If you want to take short cuts with toxic chemicals, read up on them first. I know, a lot of the old timers used them for years. A lot of them aren't around to enjoy shooting anymore. Friend of mine who used to own a body shop took a lot of short cuts. He was waiting for a heart/lung transplant before he died.
RE: MEK, Read below and decide if you want to use something that toxic. If so, do it outside and stay upwind.
Briefly, what do I need to know about methyl ethyl ketone in an emergency situation?
Methyl ethyl ketone (MEK) is a colourless liquid with a sweet/sharp, fragrant, acetone-like odour. It is an EXTREMELY FLAMMABLE LIQUID AND VAPOUR. The vapour is heavier than air and may spread long distances and distant ignition and flashback are possible. MEK is highly volatile. It is irritating to eyes and respiratory tract and a central nervous system depressant. High vapour concentrations may cause headache, nausea, dizziness, drowsiness, incoordination and confusion. MEK also causes eye irritation. It is an aspiration hazard. Swallowing or vomiting of the liquid may result in aspiration into the lungs. MEK is a POSSIBLE REPRODUCTIVE HAZARD - may cause fetotoxicity based on animal data.
RE: ACETONE
How can acetone affect my health?
If you are exposed to acetone, it goes into your blood which then carries it to all the organs in your body. If it is a small amount, the liver breaks it down to chemicals that are not harmful and uses these chemicals to make energy for normal body functions. Breathing moderate- to-high levels of acetone for short periods of time, however, can cause nose, throat, lung, and eye irritation; headaches; light-headedness; confusion; increased pulse rate; effects on blood; nausea; vomiting; unconsciousness and possibly coma
